2010 Ford Escape XLT - Rough Idling and Engine Codes

I have a 2010 Ford Escape XLT with a 2.5L engine and 235,000 miles on it. Yesterday, the check engine light came on, and the vehicle started idling rough, with a noticeable lack of acceleration, making it feel bogged down. Today, it seems to be running okay, and the check engine light has turned off. However, I pulled the following codes:

  • P0301: Cylinder 1 misfire
  • P06B8: Internal control module NVRAM errors

What do these codes indicate, and are any of these issues relatively easy to fix? Any advice on what might be causing these problems or how to proceed would be greatly appreciated!
